sorry i pasted wrong questn unser 2..
the real question is
which file will get closed through fclose()
#include<stdio.h>
int main()
{
FILE *fp,*fs,*ft;
fp=fopen("a.c","r");
fs=fopen("b.c","r");
ft=fopen("c.c","r");
fclose(fp,fs,ft);
return 0;
}
3. yes it is feof..srry typed it wrong... nd fgets(str,80,fp) is perfectly
fine.. now the ans to this questn is that last line of the file will be
printed twice...( which i m unable to get why)...plzz explain...
@ souravsain plzz ignore this mail..srry for the inconvenience..
